Linear modulation techniques are not bandwidth efficient.

Question

Quizplus · Accepted Answer

Linear modulation techniques, such as amplitude modulation (AM), frequency modulation (FM), and phase modulation (PM), can be designed to be bandwidth efficient, especially when compared to non-linear modulation techniques. Techniques like single-sideband (SSB) modulation (a variant of AM) and various forms of digital modulation that use linear processes can optimize bandwidth usage.
